Latest bushfire victim was on the phone to his brother when flames engulfed his home

The death toll from NSW's unprecedented bushfire season has climbed to 25 after the body of a 59-year-old man was found in a home on the state's South Coast.

Michael Clarke was reportedly on the phone to his brother when fire closed in on his property in Bodalla, southwest of Moruya, on Thursday.

His neighbour told Nine News he was contacted by Mr Clarke’s brother Thursday afternoon after the line cut off during a conversation they were having.

Moments beforehand, Mr Clarke told his brother the shed on his property had gone up in flames, the neighbour told the network.

The fire reportedly surrounded his property within just an hour, giving Mr Clarke limited opportunity to save himself.

The neighbour said his son thought Mr Clarke was “Australia epitomised”, describing him a “great guy”.

NSW Police said his remains were found on Friday after the bushfire raged through the area on Thursday.

“Officers located human remains in the home which had been completely destroyed by fire,” a police spokesperson said in a statement.
